BMW M3 S14 Engine
The BMW S14 is arguably the most successful touring car engine in history. Derived from the M10 block and the M88 (M1) head (minus two cylinders), it was specifically engineered to allow the E30 M3 to dominate Group A racing.
In 2026, the S14 has moved beyond a “high-performance engine” to a blue-chip collectible. Prices for parts and complete units have reached levels that make it one of the most expensive four-cylinder engines in the world.
